BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates in general to data processing systems and, in particular, to a data processing system and method providing for remotely recovering a primary password required to complete a boot process of a client computer system. Still more particularly, the present invention relates to a data processing system and method for remotely recovering a primary password required to complete a boot process of a client computer system in response to a successful execution of an interrogative password method.

2. Description of the Related Art

Personal computer systems are well known in the art. They have attained widespread use for providing computer power to many segments of today'modern society. Personal computers (PCs) may be defined as a desktop, floor standing, or portable microcomputer that includes a system unit having a central processing unit (CPU) and associated volatile and non-volatile memory, including random access memory (RAM) and basic input/output system read only memory (BIOS ROM), a system monitor, a keyboard, one or more flexible diskette drives, a CD-ROM drive, a fixed disk storage drive (also known as a “hard drive”), a pointing device such as a mouse, and an optional network interface adapter. One of the distinguishing characteristics of these systems is the use of a motherboard or system planar to electrically connect these components together. Examples of such personal computer systems are IBM'PC 300 series, Aptiva series, and Intellistation series.

A computer system requires a basic input/output system (BIOS) in order to operate. The BIOS is code that controls basic hardware operations, such as interactions with disk drives, hard drives, and the keyboard.

When a computer is reset, a boot process begins when POST begins executing. POST uses the initialization settings to configure the computer. BIOS then controls the basic operation of the hardware utilizing the hardware as it was configured by POST. The boot process is complete upon the completion of the execution of the POST commands.

In known systems, after the system has completed its boot process, a password is sometimes used to restrict the use of the system. After the system has been initialized, a user is prompted to enter the correct password. If the correct password is entered, the system will permit access by the user and boot the operating system. If an incorrect password is entered, the system will prohibit access.

One of the largest cost problems today for a large corporate information technology (IT) organization is passwords lost by users. When a user has forgotten their password, the user must call the IT help desk and get a new password. Alternatively, a service technician from the IT department may have to physically go to the user'computer system and reset the system so that the user may enter a new password.

Therefore a need exists for a data processing system and method for recovering a client computer system's primary password from a server computer system prior to the client computer system completing a boot process.

SUMMARY OF THE INVENTION

A data processing system and method are disclosed for remotely recovering a client computer system'primary password. The primary password must be correctly entered prior to the client computer system becoming fully accessible to a user. The client computer system is coupled to a server computer system utilizing a network. Prior to the client computer system completing a boot process, a user is prompted to enter the primary password. An interrogative password method is provided in response to an incorrect entry of the primary password. The primary password is recoverable in response to a successful execution of the interrogative password method. The primary password is recoverable from the server computer system by the client computer system prior to the client computer system completing the boot process utilizing the interrogative password method.

The above as well as additional objectives, features, and advantages of the present invention will become apparent in the following detailed written description.

DESCRIPTION OF A PREFERRED EMBODIMENT

A preferred embodiment of the present invention and its advantages are better understood by referring to FIGS. 1-7 of the drawings, like numerals being used for like and corresponding parts of the accompanying drawings.

The present invention is a method and system for remotely recovering a client computer system's primary password. The client computer system is coupled to a server computer system utilizing a network.

A primary password is established for a client computer system by a user. The primary password must be correctly entered during a boot process of the client in order for the client to complete its boot. If the primary password is not correctly entered, the client will be unable to complete booting, and access to the client will be prohibited.

An alternative password method is described and may be invoked upon an inability to correctly enter the primary password. The alternative password method is an interrogative method which is executed during the client's boot process, and prior to the completion of the boot process. The interrogative method is utilized by a user when the user has been unable to supply the correct primary password. If the interrogative method is executed correctly, the primary password will be supplied remotely by the server.

The interrogative password method includes prompting a user for the answer to a challenge question. If the challenge question is answered correctly, the interrogative method is executed correctly, and the server will supply the primary password. The client will then complete its boot process.

The question and expected answer the client utilizes during the interrogative method are originally supplied by a user. The question and answer are then transmitted by the client to the server along with a client identifier which identifies the particular client supplying the question and answer. The server then stores the question and answer along with the client identifier to associate the question and answer with this client.

When a client is executing a boot process, if the primary password is not entered correctly, the client will transmit a request to the server for the client's question and answer pair. The server then transmits the question to the client, which then prompts the user for the answer by displaying the question. Once an answer is entered, the client then transmits the answer to the server. The server will compare the received answer with the expected answer. If they are the same, the server will transmit the client's primary password to the client. The client will then be able to complete its boot process.

Transmissions between the client and server are encrypted utilizing an encryption device which includes secure storage. Utilizing the encryption device, the client will encrypt its transmissions with the client's private key and the server's public key. The server will then decrypt the transmissions received from the client with the client's public key and the server's private key. Likewise, the server will encrypt its transmissions to the client with the server's private key and the client's public key. The client will then decrypt the transmissions received from the server with the server's public key and the client's private key.

FIG. 1 illustrates a pictorial representation of a network including a plurality of client computer systems 104 coupled to a server computer system 100 utilizing a hub 102 in accordance with the method and system of the present invention. Server computer system 100 is connected to a hub 102 utilizing a local area network (LAN) connector bus 106. Respective client computer systems 104 also connect to hub 102 through respective LAN busses 106. The preferred form of the network conforms to the Ethernet specification and uses such hubs and busses. It will be appreciated, however, that other forms of networks may be utilized to implement the invention.

FIG. 2A depicts a more detailed pictorial representation of a client computer system in accordance with the method and system of the present invention. Client computer system 104 includes a planar (also commonly called a motherboard or system board) which is mounted within client 104 and provides a means for mounting and electrically interconnecting various components of client 104 including a central processing unit (CPU) 200, system memory 206, and accessory cards or boards as is well known in the art.

CPU 200 is connected by address, control, and data busses 202 to a memory controller and peripheral component interconnect (PCI) bus bridge 204 which is coupled to system memory 206. An integrated drive electronics (IDE) device controller 220, and a PCI bus to Industry Standard Architecture (ISA) bus bridge 212 are connected to PCI bus bridge 204 utilizing PCI bus 208. IDE controller 220 provides for the attachment of IDE compatible storage devices, such a removable hard disk drive 222. PCI/ISA bridge 212 provides an interface between PCI bus 206 and an optional feature or expansion bus such as the ISA bus 214. PCI/ISA bridge 212 includes power management logic. PCI/ISA bridge 212 is supplied power from battery 244 to prevent loss of configuration data stored in CMOS 213.

A PCI standard expansion bus with connector slots 210 is coupled to PCI bridge 204. PCI connector slots 210 may receive PCI bus compatible peripheral cards. An ISA standard expansion bus with connector slots 216 is connected to PCI/ISA bridge 212. ISA connector slots 216 may receive ISA compatible adapter cards (not shown). It will be appreciated that other expansion bus types may be used to permit expansion of the system with added devices. It should also be appreciated that two expansion busses are not required to implement the present invention.

An I/O controller 218 is coupled to PCI-ISA bridge controller 212. I/O controller 218 controls communication between PCI-ISA bridge controller 212 and devices and peripherals such as floppy drive 224, keyboard 226, and mouse 228 so that these devices may communicate with CPU 200.

PCI-ISA bridge controller 212 includes an interface for a flash memory 242 which includes an interface for address, data, flash chip select, and read/write. Flash memory 242 is an electrically erasable programmable read only memory (EEPROM) module and includes BIOS that is used to interface between the I/O devices and operating system.

Client computer system 104 includes a video controller 246 which may, for example, be plugged into one of PCI expansion slots 210. Video controller 246 is connected to video memory 248. The image in video memory 248 is read by controller 246 and displayed on a monitor (not shown) which is connected to computer system 104 through connector 250.

Computer system 104 includes a power supply 240 which supplies full normal system power 243, and has an auxiliary power main AUX 5 241 which supplies full time power to the power management logic 212.

In accordance with the present invention, the planar includes an encryption device 261 which includes an encryption/decryption engine 260 which includes an encryption/decryption algorithm which is utilized to encode and decode messages transmitted and received by the planar, and protected storage 262. Engine 260 can preferably perform public\private key encryption. Engine 260 may access a protected storage device 262. Protected storage device 262 is accessible only through engine 260. Storage device 262 cannot be read or written to by the CPU, device 222, or any other device in the system. The client's unique identifier and its encryption key pair are stored within storage 262. Everything stored in storage 262 is protected by engine 260 and is not directly accessible to the planar or its components. Device 262 may be implemented utilizing an electronically erasable storage device, such as an EEPROM. Access may be gained to non-readable storage device 262 in order to initially store the client private key. However, after the client private key is stored, it cannot be read. The keys stored in EEPROM 262 may not be read by any component of the planar other than engine 260.

Encryption algorithms are known to ensure that only the intended recipient of a message can read and access the message. One known encryption algorithm is an asymmetric, or public key, algorithm. The public key algorithm is a method for encrypting messages sent from a first computer system to a second computer system. This algorithm provides for a key pair including a public key and a private key for each participant in a secure communication. This key pair is unique to each participant. Examples of such an encryption scheme are an RSA key pair system, and a secure sockets layer (SSL) system.

In accordance with the present invention, encryption device 261, including engine 260 and EEPROM 262, is coupled to PCI-ISA bridge 212 utilizing a system management (SM) bus 238. System management bus 238 is a two-wire, low speed, serial bus used to interconnect management and monitoring devices. Those skilled in the art will recognize that encryption device 261 may be coupled to another bus within the planar.

Client 104 also includes a network adapter 230. Network adapter 230 includes a physical layer 234 and a media access controller (MAC) 232 coupled together utilizing a Media Independent Interface (MII) bus 252. The MII bus 252 is a specification of signals and protocols which define the interfacing of a 10/100 Mbps Ethernet Media Access Controller (MAC) 232 to the underlying physical layer 234. Network adapter 230 may be plugged into one of the PCI connector slots 210 (as illustrated) or one of the ISA connector slots 216 in order to permit client 104 to communicate with server 100 utilizing a communication link 106.

MAC 232 processes digital network signals, and serves as an interface between a shared data path, i.e. the MII bus 252, and the PCI bus 208. MAC 232 performs a number of functions in the transmission and reception of data packets. For example, during the transmission of data, MAC 232 assembles the data to be transmitted into a packet with address and error detection fields. Conversely, during the reception of a packet, MAC 232 disassembles the packet and performs address checking and error detection. In addition, MAC 232 typically performs encoding/decoding of digital signals transmitted over the shared path and performs preamble generation/removal, as well as bit transmission/reception. In a preferred embodiment, MAC 232 is an Intel 82557 chip. However, those skilled in the art will recognize that the functional blocks depicted in network adapter 230 may be manufactured utilizing a single piece of silicon.

Physical layer 234 conditions analog signals to go out to the network via an R45 connector 236. Physical layer 234 may be a fully integrated device supporting 10 and 100 Mbps CSMA/CD Ethernet applications. Physical layer 234 receives parallel data from the MII local bus 252 and converts it to serial data for transmission through connector 236. Physical layer 234 is also responsible for wave shaping and provides analog voltages. In a preferred embodiment, physical layer 234 is implemented utilizing an Integrated Services chip ICS-1890.

Physical layer 234 includes auto-negotiation logic that serves three primary purposes. First, it determines the capabilities of client 104. Second, it advertises its own capabilities to server 100. And, third, it establishes a connection with server 100 using the highest performance connection technology.

FIG. 2B illustrates a pictorial representation of special purpose processing unit 300 which is included within a network adapter 230 included within a client computer system 104 in accordance with the method and system of the present invention. Special purpose processing unit is preferably implemented utilizing an ASIC 300 which includes a micro-controller 302 which includes several state machines to handle the following tasks: packet reception, SM bus interface, and BEPROM updates. Micro-controller 302 sends commands to FIFO control 308 to control data flow from TX FIFO 306, RX FIFO 310, and RX Buffer 318. Micrb-controller 302 also responds to SM bus requests from software running on client 104 to access register status 304 or access EEPROM 320. Signals are received from the MII bus 252 by interface unit 312 and passed to RX FIFO 310.

Micro-controller 302 accesses EEPROM 320 through EEPROM interface 314 to obtain values to create network packets such as source and destination MAC addresses, IP protocol information, authentication headers, and Universal Data Packet headers. Further, EEPROM 320 retains the Universal Unique Identifier (UUID).
